Abstract: A three-dimensional (3D) metal object manufacturing apparatus selects operational parameters for operation of the printer to form conductive metal traces on substrates with dimensions within appropriate tolerances and with sufficient conductive material to carry electrical currents without burning up or becoming too hot. The apparatus identifies the material of the substrate and the bulk metal being melted for ejection and uses this identification data to select the operational parameters. Thus, the apparatus can form conductive traces and circuits on a wide range of substrate materials including polymeric substrates, semiconductor materials, oxide layers on semiconductor materials, glass, and other crystalline materials.

Abstract: A method for printing a structure, the structure including a plurality of pillars. The method for printing can include ejecting only a first drop of a print material such as a liquid metal sequentially at each of a plurality of pillar locations, then ejecting only a second drop of the print material sequentially onto the first drop at each of the plurality of print locations. Additional drops can be ejected at two or more of the pillar locations to form the plurality of pillars. Ejecting only a first drop at each pillar location allows the first drop to cure (i.e., cool or dry) before ejecting the second drop. The printer continues printing while the drops cure, thus improving processing efficiency and increasing production throughput.

Abstract: A method operates a three-dimensional (3D) metal object manufacturing system to compensate for displacement errors that occur during object formation. In the method, image data of a metal object being formed by the 3D metal object manufacturing system is generated prior to completion of the metal object and compared to original 3D object design data of the object to identify one or more displacement errors. For the displacement errors outside a predetermined difference range, the method modifies machine-ready instructions for forming metal object layers not yet formed to compensate for the identified displacement errors and operates the 3D metal object manufacturing system using the modified machine-ready instructions.

Abstract: A metal object manufacturing apparatus is configured to eject melted metal drops to form a continuous metal line over a line of spatially separated pillars in a single pass. The ejection frequency for forming the continuous metal line is different than the frequency used to form the pillars. In one embodiment, the ejection frequency for forming the pillars is about 100 Hz and the frequency used to form the continuous metal line over the line of spatially separated pillars is about 300 Hz with a drop spacing of about 0.2 mm. Continuous metal lines are formed to extend the continuous metal lines over the pillars laterally to fill the gaps between the continuous metal lines over the pillars. These continuous metal lines that fill the gaps are formed while operating the ejection head at the 300 Hz frequency with a drop spacing of 0.28 mm.
